Detailed description of the invention
Describing the present invention below according to accompanying drawing, it is that the one in numerous embodiments of the present invention is the most real
Execute example.
In a preferred embodiment, a kind of drive system for Diesel engine high-pressure oil pump, it is arranged on cylinder head
On high-pressure oil pump engage each other transmission by a pair gear of tail end of camshaft.This camshaft front end is provided with sprocket wheel, this chain
Wheel is connected with crankshaft sprocket by chain, thus during engine crankshaft rotation, drives high-pressure oil pump to rotate.
In a further advantageous embodiment, following scheme can be used: a kind of biography for Diesel engine high-pressure oil pump
Dynamic system, high-pressure oil pump is arranged in cylinder head, and it engages each other transmission by a pair gear of tail end of camshaft.Gear and height
Pressure oil pump cavity rotates coaxially, and is follower, and the gear of tail end of camshaft is drivewheel, and both engage each other, and this is gear pair
1.According to the performance requirement of oil pump, its rotating speed can be adjusted by the difference of number of gear teeth.
In order to ensure the connection fastening between drivewheel and camshaft, use the connected mode of hot pressing dress between the two；With
Time, in order to reduce the noise in transmission process, gear pair 1 uses a pair helical teeth to coordinate.The camshaft front end driving oil pump is installed
Having sprocket wheel, this camshaft sprocket is connected by chain 7 and crankshaft sprocket 8, i.e. timing driving system.In order to ensure timing transmission system
The reliability of system, native system uses single sprocket chain, chain, the compact Layout structure of guide rail and stretcher.For only connecting two chains
For the timing system of wheel, chain cornerite on sprocket wheel is relatively big, does not haves the situation jumping tooth (sprocket wheel and chain disengage)；With
Time, it is bigger that the guide rail radius of the radian between sprocket wheel can design, thus reduces frictional resistance when chain runs on guide rail.
As it is shown in figure 1, in order to make timing system compact conformation, use and be threaded into formula stretcher, to reduce at electromotor
On installing space demand, according to the performance requirement of whole drive system, stretcher passes through appropriate design, reduces system tension,
Thus system friction resistance can also be reduced.As it is shown in figure 1, the drive cam shaft front end of high-pressure oil pump is provided with timing sprocket,
Fix between mode and camshaft 1 that this sprocket wheel is fastened by bolts.As it is shown in figure 1, use the diesel oil of Dual Over Head Camshaft to send out
Motivation typically uses admission cam shaft and exhaust cam shaft to drive inlet valve and exhaust valve respectively.For diesel engine, its combustion
Burning room is typically on piston, and typically no on cylinder cap, therefore valve angle is comparatively small, close together between two camshafts.Separately
An outer camshaft uses the mode transmission of a pair gear engagement, and the number of teeth is identical, and direction of rotation is contrary, i.e. gear pair 2.Such as Fig. 1
Shown in, crankshaft sprocket, camshaft sprocket direction of rotation is (in terms of motor head) clockwise, high-pressure oil pump gear and camshaft
2 rotation modes are counterclockwise.The camshaft and the timing sprocket place camshaft that drive oil pump are same.Shown in Fig. 1 not
Specify inlet and outlet camshaft location, the system that the most every employing is similar with this structure, all should the protection domain of this structure it
In.
As it is shown in figure 1, a kind of drive system for Diesel engine high-pressure oil pump, it is arranged on the hydraulic oil in cylinder head
Pump engages each other transmission by a pair gear of tail end of camshaft.This camshaft front end is provided with sprocket wheel, and this sprocket wheel passes through chain
It is connected with crankshaft sprocket, thus during engine crankshaft rotation, drives high-pressure oil pump to rotate.This system comprises the timing of electromotor
Chain conveyer and distribution cam axle two great institutions.In general, oil pump is driven by the connection of camshaft front and back end, can be by driving
The number of teeth of moving gear, the rotating speed of regulation oil pump, thus realize the control to common rail pressure.The invention provides another one high pressure
The installation solution of oil pump.
As it is shown in figure 1, electromotor uses dual overhead camshaft configuration, owing to the combustor of diesel engine is all on piston, cylinder
Cover almost without, so inlet and outlet door angle is relatively small, the spacing causing inlet and outlet camshaft is less.For solving to pass
Dynamic problem, uses a pair gear drive (Fig. 1 gear pair 2) between inlet and outlet camshaft, the number of teeth is identical, and rotation direction is contrary.For
Ensure the connection tightness between camshaft and gear, use the mode of hot pressing dress, i.e. heat gear to necessarily between the two
Temperature, according to the principle expanded with heat and contract with cold, now installs on camshaft.Meanwhile, in order to ensure that port timing is accurate, camshaft is installed
During gear, use alignment pin to position, see accompanying drawing 2.
Timing chain can only drive air inlet or exhaust cam shaft, for high-pressure oil pump, during its work, needs the torsion consumed
Square is relatively big, therefore uses same camshaft drive, i.e. this camshaft front end to install timing sprocket, has timing chain directly to drive
Dynamic, the direct geared of rear end drives high-pressure oil pump.Similarly, for ensureing to connect fastening, rear end directly drives the driving tooth of oil pump
The mounting means of hot pressing dress it is also adopted by between wheel and camshaft.
High-pressure oil pump is bolted and is fixed on engine cylinder cover back-end, in order to reduce valve actuating mechanism and high-pressure oil pump group
Close the load of work, when oil pump is installed, the peak torque of the high-pressure oil pump that needs to stagger and the peak load point of camshaft.
When camshaft drives without additional high pressure oil pump, (the matching as shown in table 1 of the torque curve (four cylinder engine) during work
Curve).It can be seen that four cylinder engine camshaft turns around, there are four torque peak high point and four peak torques
Low spot.Being separated by 90 degree between adjacent peak high point, being separated by between adjacent peak low spot is also 90 degree.
As shown in table 2, during operation of oil pump, rotate one circle, (this oil pump has three operation of oil pump chambeies), between peak value high point between
Being divided into 120 degree, peak value low spot interval is also 120 degree.
If installing initial position lucky oil pump peak torque point and the coincidence of camshaft torque peak high point, then will increase
The peak torque of big cam axle, thus increase timing chain load.This is that we are not intended to see.
From above-mentioned condition analysis, if high-pressure oil pump peak torque point fall behind camshaft torque peak torque point 30 degree, 60
Spend or 90 degree, then in the follow-up situation that peak value superposition necessarily occurs.By analytical calculation, when first peak point of oil pump falls behind
First peak point of camshaft 15 degree, then can realize without peak torque superposition.It is as shown in table 3 that both close torque curve.
The connected mode of centre bolt fastening is used, such as accompanying drawing 3 between timing sprocket and camshaft.The fastening force of this bolt
Square MbThe whole loads meeting valve actuating mechanism and high-pressure oil pump are needed to calculate, it is ensured that bolt clipping forcee can overcome whole
Load, it is to avoid occur in the course of the work relatively rotating between sprocket wheel and camshaft or bolt, it may be assumed that
Mb>=Mc+Mh
Wherein
McCamshaft operation torque
MhOperation of oil pump moment of torsion
Mb, after bolt is tightened, the moment of resistance that the normal pressure between its flange face and sprocket wheel produces
During Calculating Torque during Rotary, it is considered to gearing efficiency and factor of safety.
As it was previously stated, close together between diesel engine inlet and outlet camshaft, spatially cannot use two camshaft sprockets
Transmission respectively, can only use a camshaft sprocket and crankshaft sprocket transmission.The advantage of this point this system the most exactly.Because
After using a camshaft sprocket and a crankshaft sprocket, whole timing system is arranged simple, compact, chain bag on sprocket wheel
Angle is bigger, it is not easy to produce slippage phenomenon (disengaging between chain and sprocket wheel in operation).Meanwhile, during design chain guide, guide rail
Curvature is relatively big, reduces friction loss when chain runs and between guide rail.
For diesel engine, its workload is relatively big, and in cylinder, explosion pressure is high, and timing chain needs to use strength grade
Higher material；The crankshaft sprocket number of teeth is difficult on the low side, on the low side if, its polygon effect is obvious, causes torsional oscillation to increase；Meanwhile,
The number of teeth also has direct relation with camshaft center to crankshaft center distance.Comprehensive many factors, set crankshaft sprocket as
21 teeth, camshaft sprocket is 42 teeth.
This timing chain and high-pressure oil pump drive system job stability, the biggest factor depends on design of tensioners.Tensioning
Device characteristic has bigger snapback area (see accompanying drawing 4), thus local abatement is due to bent axle, camshaft, high-pressure oil pump work
The vibration that uneven stability during work is brought.
It has been observed that high-pressure oil pump and camshaft, between two camshafts and bent axle, clear and definite timing phase relation is had to want
Ask.When phase relation between bent axle and camshaft is by installing, fixed crankshaft and camshaft realize, high-pressure oil pump and camshaft
Between, realize by the way of the alignment of the mark point on gear in time installing.
Above in conjunction with accompanying drawing, the present invention is exemplarily described, it is clear that the present invention implements not by aforesaid way
Restriction, as long as have employed method design and the various improvement that carry out of technical scheme of the present invention, or the most improved direct application
In other occasion, all within protection scope of the present invention.
